Abstract
The invention relates to the steelmaking converter equipment technical field, in particular to a movable smoke hood sealing device of a steelmaking converter. The movable smoke hood sealing device overcomes the defects that the prior converter movable smoke hook sealing technology has high nitrogen consumption and high nitrogen content in coal gas. The invention provides a movable smoke hood sealing device of the steelmaking converter. The movable smoke hood sealing device comprises a movable smoke hood, a movable smoke hood protective flange and a fixed flue; the movable smoke hood and the movable smoke hood protective flange which is welded with the movable smoke hood into a whole are concentrically sleeved on the outer wall of the fixed flue; the outer wall of the fixed flue is annularly provided with a follow-up sealing ring; and the follow-up sealing ring is arranged on the top of the movable smoke hood protective flange. The movable smoke hood sealing device uses a simple mechanical method to solve the sealing problem of the movable smoke hood of the converter, reduces the nitrogen content in the coal gas and improves the quality of the coal gas.
Description
Technical field
The present invention relates to the steel-making converter equipment technical field, be specifically related to a kind of steel-smelting converter movable smoke hood sealing arrangement.
Background technology
Present known converter movable hood adopts the nitrogen-sealed technology, is the modern technique that replaces sealing structure for water, but still exist converter movable hood and converter fixedly between the flue gap big, nitrogen consumption height, the high defective of nitrogen content in the coal gas composition.
Summary of the invention
In order to overcome the high defective of nitrogen content in existing converter movable hood nitrogen-sealed technology nitrogen consuming amount height, the coal gas, the invention provides a kind of steel-smelting converter movable smoke hood sealing arrangement, this technology is Maintenance free not only, and nitrogen consumes little, use cost is low, and can improve the quality that reclaims coal gas.
In order to achieve the above object, the invention provides a kind of steel-smelting converter movable smoke hood sealing arrangement, comprise movable gas hood, movable gas hood protection flange and fixing flue, movable gas hood and the movable gas hood protection flange concentric locking collar that is welded as a whole with it are loaded on fixedly flue outer wall, its special character is: described fixedly flue outer wall is around being provided with the Follow-up seal circle, the Follow-up seal circle be arranged on movable gas hood protection flange above; Described Follow-up seal circle is made up of around the monomeric servo sealer of arranging plurality of continuous; Described servo sealer is made up of sealing steel plate, spring assembly and roller frame, described sealing steel plate is arranged between spring assembly and the movable gas hood protection flange, and fixedly the overwhelming majority in space is blocked between flue outer wall and the movable gas hood protection flange, makes the leakage area of flue gas reduce to minimum; One end of described spring assembly is connected with roller frame, described roller frame is close to fixedly flue outer wall, the power of the vertical direction of flue outer wall is unlikely to too big to make servo sealer be subjected to fixedly, thereby guarantees that sealing steel plate and movable gas hood protection flange keep relation of following up on vertical surface; The other end of described spring assembly is fixedlyed connected with the movable gas hood protection flange outside by the retaining thread web member; spring assembly is pushed the roller frame and the sealing steel plate of servo sealer to fixedly flue outer wall; make the sealing steel plate on horizontal plane, form relation of following up with fixing flue, thus the assurance sealing effectiveness.
Above-mentioned spring assembly is provided with guide frame, keeps the rigidity of spring assembly on vertical surface, thereby guarantees that sealing steel plate and movable gas hood protection flange keep relation of following up on vertical surface, thereby guarantees sealing effectiveness.
The plane of above-mentioned sealing steel plate is a sector shape.
Compared with prior art, the beneficial effect of the present invention's generation is as follows:
The present invention solves the converter movable hood sealing problem with simple mechanical means, reduces a nitrogen content in the coal gas, improves gas quality.

Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Referring to Fig. 1; Fig. 2; the invention provides a kind of steel-smelting converter movable smoke hood sealing arrangement; comprise movable gas hood 6, movable gas hood protection flange 5 and fixing flue 7; movable gas hood 6 and movable gas hood protection flange 5 concentric locking collars that are welded as a whole with it are loaded on fixedly flue 7 straight cylindrical outer wall; described fixedly flue 7 outer walls are around being provided with the Follow-up seal circle, the Follow-up seal circle be arranged on movable gas hood protection flange 5 above.Described Follow-up seal circle is made up of around the monomeric servo sealer of arranging plurality of continuous.
Referring to Fig. 2, the monomeric servo sealer of being made up of sealing steel plate 1, spring assembly 4 and roller frame 3 is around the fixing flue 7 straight cylindrical outer wall layouts of converter, and the dependence own wt drops on movable gas hood and protects above the flange 5.
Sealing steel plate 1 in the described servo sealer is arranged between spring assembly 4 and the movable gas hood protection flange 5, and fixedly flue 7 outer walls protect the overwhelming majority in space between the flange 5 to block with movable gas hood, make the leakage area of flue gas reduce to minimum; One end of described spring assembly 4 is connected with roller frame 3, described roller frame 3 is close to fixedly flue 7 outer walls, the power of the vertical direction of flue outer wall is unlikely to too big to make servo sealer be subjected to fixedly, thereby guarantees that sealing steel plate 1 and movable gas hood protection flange 5 keep relation of following up on vertical surface; The other end of described spring assembly 4 is fixedlyed connected with movable gas hood protection flange 5 outsides by retaining thread web member 2; spring assembly 4 is pushed the roller frame 3 and the sealing steel plate 1 of servo sealer to fixedly flue outer wall; make sealing steel plate 1 and fixing flue 7 on horizontal plane, form relation of following up, thereby guarantee sealing effectiveness.
Described spring assembly 4 is provided with guide frame 8; keep the rigidity of spring assembly on vertical surface; guarantee sealing steel plate 1 can be the most closely near fixing flue; sealing steel plate 1 section has certain altitude; thereby guarantee when movable gas hood 6 liftings; described sealing steel plate 1 keeps relation of following up with movable gas hood protection flange 5 on vertical surface, thereby guarantees sealing effectiveness.
Referring to Fig. 3, sealing steel plate 1 plane of each servo sealer is a sector shape.
The above only is preferred embodiment of the present invention, and not in order to restriction the present invention, common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacement all should be included in protection scope of the present invention.
